Gallery in the Great Pyramid
The Great Gallery is also of curious construction. Extending for a distance of one hundred and fifty feet, and rising at an angle of 26° 18', it has a width of five feet at the base and a height of above thirty feet. The side walls are formed of seven layers of stone, each projecting a few inches over that below it. The gallery thus gradually contracts towards the top, which has a width of four feet only, and is covered in with stones that reach across it, and rest on the walls at either side. The exact object of so lofty a gallery has not been ascertained; but it must have helped to keep the air of the interior pure and sweet, by increasing the space through which it had to circulate.
Great Hall of Columns at Karnak (Restored)
The greatest of all Seti's works was his pillared hall at Karnak, the most splendid single chamber that has ever been built by any architect, and, even in its ruins, one of the grandest sights that the world contains. Seti's hall is three hundred and thirty feet long, by one hundred and seventy feet broad, having thus an internal area of fifty-six thousand square feet, and covers, together with its walls and pylons, an area of eighty-eight thousand such feet, or a larger space than that covered by the Dom of Cologne, the largest of all the cathedrals north of the Alps. It was supported by one hundred and sixty-four massive stone columns, which were divided into three groups—twelve central ones, each sixty-six feet high and thirty-three feet in circumference, formed the main avenue down its midst; while on either side, two groups of sixty-one columns, each forty-two feet high and twenty-seven round, supported the huge wings of the chamber, arranged in seven rows of seven each, and two rows of six. The whole was roofed over with solid blocks of stone, the lighting being, as in the far smaller hall of Thothmes III., by means of a clerestory.
